Jonas, does it actually know how to look into /target/etc/fstab and not /etc/fstab ? > > d-i currently does this before installing mkinitrd-tools: > > > > # Temporarily hardcode the root partition. > > rootpart_devfs=$(mount | grep "on /target " | cut -d' ' -f1) > > rootpartfs=$(mount | grep "on /target " | cut -d' ' -f5) > > rootpart=$(mapdevfs $rootpart_devfs) > > if [ -f $mkinitrdconf ]; then > > sed -e "s#^ROOT=.*#ROOT='$rootpart $rootpartfs'#" < > > $mkinitrdconf > $mkinitrdconf.new && > > mv $mkinitrdconf.new $mkinitrdconf > > else > > echo "ROOT='$rootpart $rootpartfs'" >> $mkinitrdconf > > fi > > > > Appacently Colin has already checked that initramfs-tools doesn't > > need such a hack, > > Right; Jeff Bailey has been very clear to me that it can work it out > based on what it's told by the bootloader. > > Some lilo modifications may be needed at some point to pass the root > filesystem as a device name rather than in lilo's hex-encoded > major/minor form (which I'm told will eventually break due to kernel > changes, and probably doesn't work so well for wacky block devices even > now), either by changing lilo directly to do that or just by making > lilo-installer override it by adding root= to the kernel command line in > append=. initramfs-tools does handle lilo's current syntax for the > moment, though. What about the wide variety of non-x86 boot loaders ? What about the prep case, where you cannot set default args appart from the kernel command line ? I still think that having the ramdisk content hardcode the root path (overridable on the command line) is a more secure way of doing this.
